We stay for at least eight hours with our colleagues in every working day, much longer than time we spend with our families and friends. but do you think a colleague can really become a friend? we can talk everything with our friends, but we cannot do that with our colleagues because we work together, we have similar goal to fight for. We only hope our colleagues won't become our enemies, so that if they can stay peacefully with us, we feel relaxed and don't hope extravagantly that they can become our friends.
